I have... I think the last count of the protecting you 'verse characters had me at aboooooooooout 250 of them.
UM.
Some turn up to do a job for a chapter and are gone again! Others - well, I've got a council of Cephiro and a bunch of politicians and (at least one) assassin etc etc etc.
The two who have started turning up in other fic (and totally have a sidefic of their own but it's made of spoilers so only Mils has read it) are Zafira, the new Soru, who is very BY THE BOOK about - everything - and stern, and looks rather like Zagato's ghost from a distance, which really doesn't help with the damage control she's having to do to get anything done. Not wearing a white set of the same priests robes as he usually did isn't helping but mostly people are too nervous of her to get close enough they'd tell her. Clef doesn't know what to make of her, the feeling is mutual.
The head of the healer's guild (Beru), Miura, is the other. Short, roundish, grumpy with people for getting themselves hurt and STOP YELLING AT MY MINIONS WHEN THEY TELL YOU YOU NEED TO SLEEP, CLEF. One of her grandparents was a water spirit which helps with her healing - she's very good at sensing what's wrong with people (after all, we're mostly water). She only usually yells at Clef. Mostly. In charge of Eagle's healing - he's a good patient, she likes Eagle, this goes away a little when he wakes up and starts pushing too hard, he gets Sternly Lectured at that point. No one can technically outrank her because she can always declare herself their healer (hi Clef) which gives automatic right to stop them doing anything too stupid to themselves, and she isnt in awe of any of the council. However she has pretty much no interest in politics and tends to think the arguing is stupid so sometimes stops paying attention when she should be. She really, really cares. And she's one of very few people of high power who survived in post through Emeraude's fall - which may well explain why she doesn't care who she yells at now, she has had enough with people's stupidity hurting others and watching all her patients go out to fight again and again and die. She has no offensive magic at all or she'd probably have snapped and gone to fight Zagato so she didn't have to watch her patients dying anymore.
She likes how straightforward Zafira is. They've been in a relationship since sometime during Emeraude's fall, well before Zafira's promotion. Not many people have noticed, even though they're actually living together by now! And both of them are very dedicated to their work, it hasn't really occured to people they might have private lives too. Though it's not a secret, everyone who has to fetch one of them for an emergency knows, they just don't get gossiped about much either. XD
They are turning up in everything now because I can't be arsed inventing people to wander through the background of things when they're already ready to go? Er. Also I might be really rather fond of Miura. XD
In a completely different vein, there is Kuregu. Who is a character I hate so much the first time I ever decided to do a sequel to protecting you it was so I could murder him, because he's an antagonist in Protecting You but not one they could actually pin anything on - he is a career politician who maintains his and his land's position by any means necessary, frequently blackmail, and I HATEEEEEEEEE HIM HE IS A NASTY THING.
..................He really does think He Knows What Is Best For Dleivus, and will impose this on the rest of the universe without compunction or morals.
Writing him getting stabbed in the back sixteen times is very cathartic!
